The FALs can be great shooters as long as you get one with a DSA or Imbel receiver. The other manufacturers have a spotty record. Some of the Century assembled FALs will need a bit of work, as they are hastily put together.
The best way to do a FAL is to buy a receiver, a parts kit, and have a smith assemble it. Usually more care is put into your rifle this way. Plus, you can customize it to your desires.
The only US-made HK clone I'd buy (that's currently on the market) is of the aluminium receivered Federal Arms type. The Hesse receiver is just too poorly made.
If you can stand the trial, you can get a FMP receiver, made under HK liscence, from InterOrdnance. Find a decent parts kit, a new barrel, some US parts (from Federal Arms), a smith to assemble and you'll have a HK quality rifle for the clone price.
